Curiosity’s Tracks Are Gone With The Wind

Mars may have an atmosphere just 1% the density of Earth’s but it can still stir up enough of a breeze to quickly cover a rover’s tracks, as evidenced in the animation above. Captured by Curiosity’s downward-looking Mars Descent Imager (MARDI) camera on Jan. 23 and 24, 2017, the two pictures show an approximately 3-foot-wide…

What Warmed Mars? The Curious Case of the Missing Carbonate

Everything we’ve observed so far about the surface of Mars points to an ancient past that was warmer, wetter, and very possibly habitable for life as we know it. From the scars of enormous floods and vast branching river deltas that are etched into the Martian surface to the rounded pebbles of ancient stream beds…

No This Is Not an Alien Cave Crab on Mars

I’m in a debunking mood today, probably brought on by the seasonal “double Moon hoax” that raises its oh-so-wrong head every August. (Read more on that nonsense here.) So here’s one more thing to say “NO” to: giant alien cave crabs on Mars. Apparently there’d been some buzz recently in the “space woo” circles online…

Curiosity Gazes on Mars’ Moon Phobos

Do you love to look up at the Moon? Well so does NASA’s Curiosity rover! Feel free to correct me if I’m wrong (I have not confirmed this) but this appears to be an image of Phobos, the larger of Mars’ two small moons, imaged by Curiosity’s Mastcam on mission Sol 1002 (June 1, 2015)….

Curiosity’s View Into Marias Pass

The image above shows Curiosity’s view southwest into “Marias Pass,” a low valley in Gale Crater where the rover was on May 22, 2015 – mission Sol 992. At the left (east) edge is the western slope of a rise called Akipuni Mountain, and Mount Shields rises off to the right (west). The image is a…

Curiosity Has Found Yet More Evidence For a Life-Lovin’ Mars

Cold as hell and no place to raise your kids, the surface of Mars today is a quite inhospitable place for any forms of life we know of. But that wasn’t always the case – billions of years ago Mars may have been a lot more like Earth, with a magnetic field, a much denser atmosphere, lakes…

Curiosity’s First “Selfie” of 2015

Here’s a “selfie” of NASA’s Curiosity rover, made from about 20 images acquired by its MAHLI instrument on mission sol 868 (January 14, 2015). I used Photoshop to stitch the raw images together and then enhanced the contrast and detail with a bit of HDR effect. (There’s one spot behind the rover’s RTG where an…

A Postcard from Mars: Salsberry Peak Panorama

Every now and then I get unexpectedly caught up in a project that I originally intended to be a quick just-for-fun thing and ends up taking an hour and a half of my time (usually long after I should have gone to bed.) This was one of those. Made up of 28 raw images acquired…

Is Mars Alive? Curiosity Uncovers Organics and Methane in Gale Crater

While it’s not quite the “smoking gun” for evidence of life on Mars, the recent announcement of a detection of spiking methane levels by NASA’s Curiosity rover has certainly caught everyone’s attention – especially since the activity of microbes is one possible source for the presence of the compound, which has already been detected by…

Curiosity Claims the Biggest Meteorite Ever Found on Mars

If you’re a heavy metal fan then you’ll love this: this shiny, lumpy rock spotted by NASA’s Curiosity rover is made mostly of iron — and came from outer space! Dubbed “Lebanon” it’s a stony iron meteorite, similar to ones found in years past by the Spirit and Opportunity rovers, but is considerably larger than any of…

Happy First Year on Mars, Curiosity!

Sol 669 is here (well, there… on Mars that is…) and that marks the one full year anniversary of Curiosity’s mission exploring Gale Crater! Wait, you say, didn’t Curiosity land on Mars in August of 2012? Shouldn’t we still be approaching the TWO-year anniversary of the MSL mission? Well, yes, here on Earth, but on…

Mercury Is Spotted For The First Time – From Mars!

NASA’s Curiosity rover may be busy exploring the rugged and rocky interior of Gale Crater but it does get a chance to skygaze on occasion. And while looking at the Sun on June 3, 2014 (mission Sol 649) the rover’s Mastcam spotted another member of our Solar System: tiny Mercury, flitting across the Sun’s face. Silhouetted against…
